Other advantages and the characteristic of device of the present invention and application thereof will be below by providing in the description of accompanying drawing to one embodiment of the present of invention.
In the accompanying drawings:
Fig. 1 illustrates the axial longitudinal section of filter of the present invention;
Fig. 2 illustrates the layout block diagram of filter in an interrupted injection equipment, and this equipment is with a kind of lubricant-suspension of high-pressure injection.
Shown in filter be used for from a kind of lubricant-suspension separating coarse-grained, and in the equipment of a kind of lubricant-suspension of interrupted injection for example of can packing into, described in the Swiss Patent application of submitting in March 26 nineteen ninety as the applicant 996/90 (not belonging to prior art) and as shown in Fig. 2.
The housing of this device is made up of middle part 3 and a top cover 4 that has circular peripheral 5 and cover bodies that raise up 6 of a base portion that has a ring flange 2, a hollow cylindrical.The wall shell that passes hollow cylindrical middle part 3 is radially stretched in the import 7 of suspension 8 to be filtered, and the outlet 9 of filtrate 10 is located at the central authorities of the cover body 6 epirelief or that heave of top cover 4.Between middle part 3 and top cover 4, dispose a filter 116 motor 12 and drive rotor 14 by transmission device 13.Rotor 14 has the parts 15 of columniform, the axial hole that passes base portion 2 and one to be configured in the middle part 3 the upwards bearing parts 16 of expansion, is supported with scraping blade 17 in the above, and it strikes off the solids of deposition on filter 11.
Filter 11 is made of a sieve that constitutes by a circle, smooth multihole lamina, and the mesh specification is 0.5 millimeter.This tabular sieve 11 removably be fixed on by screw 18 along the configuration of its peripheral intervals a circle sieve support (filter support plate) 19 below on.External diameter and the hollow cylindrical middle part 3 of sieve support 19 is identical and be clamped in its circular periphery 20 between the periphery 5 of 3 upper surfaces and top cover 4 in the middle part of the hollow cylindrical.Sieve 11 external diameter is only less than a tolerance of internal diameter at hollow cylindrical middle part 3, make sieve 11 be in sieve support 19 clamped periphery 20 within.Sieve support 19 has a plurality of through holes 21 that supply filtrate 10 to pass through in the zone of sieve 11.The sieve support is as sieve 11 gripper shoe, is perpendicular to rotor axis 22 configurations, and guarantees thin and flexible sieve 11 even still keep straight at very high input pressure during as 80 crust, and keeps perpendicular to rotor axis 22.

The import 7 that the inner chamber 24 of its axis normal in rotor axis 22 ground and hollow cylindrical middle part 3 communicates is as much as possible near the upper surface at middle part 3 thereby be to be provided with near sieve 11.To this, import 7 only need be chosen to make from distance this moment of upper surface on the shell wall at middle part 3 because the hold-down screw 18 of sieve 11 has the part of groove can keep sufficiently stable and get final product, carry out 7 positions and move down slightly vertically owing to this (being for the consideration on the strength of materials) essential distance makes with respect to scraping blade 17.Because this dislocation,, do not resemble its function and flow to whole scraping blade 17 when best, and only flow to its Lower Half by the suspension 8 that import 7 flows into.But as indicated in test, this is enough to reach and washes away the effect that is deposited on the solids on the scraping blade 17.
Radially relatively be provided with a slag liquid outlet 25 with import 7, it and the import 7 the same wall shells that pass hollow cylindrical housing middle part 3 with its longitudinal axis perpendicular to rotor axis 22 stretching, extensions.The outlet 25 of this slag liquid with one in order to discharge by scraping blade 17 from the discharge pipe or the drain tube 27 slag liquid, that dispose the switching mechanism 26 that is designed to the triple valve form of sieving 11 solids that strike off and constituting link to each other (purposes of triple valve 26 is illustrated in the time of will telling about the filter application below).Because the lower portion of scraping blade 17 is between import 7 and slag liquid outlet 25, by import 7 input suspension 8 to be filtered, and preferably under the situation of rotation, carry out slag liquid when discharging at rotor 14, a kind of eddy current around scraping blade 17 occurs, the effect by above-mentioned eddy current will wash away attached to the solids on the scraping blade 17.Since import 7 with export between 25 perpendicular to the flow direction of rotor axis 22 and the rotation of scraping blade 17, at this moment input liquid stream impact scraping blade 17 at different position of rotation with different angles respectively: be parallel to each scraping blade 17 that is positioned at import 7 places and act on its arris, and and then pour below washed in the slot 28 of the bearing part 16 that will illustrate and to it, acute angle to increase in being further rotated subsequently, and after reaching the right angle acute angle to reduce, obliquely act on the top part of the slot 28 of scraping blade 17, wherein particularly reach significant cleaning performance by the parallel liquid stream that pours slot 28 of the previous case.
Scraping blade 17 is made and can be bearing in movably vertically in radial gap 28 above the bearing part 16 of upwards expansion of rotor 14 by the polyethylene board of rectangle on and by be configured in bearing part 16 the hole in compression spring 29 exert pressure towards sieve 11.Scraping blade upwards all protrudes in by outside the slotted wall 30 formed guiding faces with the footpath in the axial direction.Each scraping blade 17 all has a pin (adjustment bolt) 31 to pass slotted wall 30 screw-ins, pin the part between the slotted wall 30 engage with scraping blade 17 greater than the hole 32 of pin diameter by the aperture on the scraping blade 17 and as restriction scraping blade 17 by the backing pins that move that 29 effects of compression spring produce, make scraping blade 17 still keep staying on the bearing part 16 of rotor when sieve 11 is pulled down sieve support 19 for cleaning or changing.According to the situation that filter residue constitutes, can be provided with one or more be star, with the scraping blade 17 of equal angular arranged spaced, and the slot of respective numbers is set at rotor top.It is suitable especially using two to four scraping blades verified actually.
Import 7 is provided with the tube connector screw thread to be connected with connecting pipe with outlet 9,25.
The inner chamber 24 and the top cover inner chamber that flow through for the liquid that seals hollow cylindrical middle part 3, base portion 2 is by two shaft seal 33 and O-ring seals 34 that are enclosed within on the base portion 2 that are enclosed within on the rotor part 15, middle part 3 by an O-ring seals 35 with sieve plate support 19 periphery 20 seal, this periphery 20 seals by the periphery 5 of an O-ring seals 36 with top cover 4 at opposite side again.
This filter can be applied in an equipment that is used for a kind of lubricant-suspension that sprays of interrupted injection under high pressure, is described as follows for helping Fig. 2:
Lubricant-suspension pumps into to come the filter from 41 suctions of an intake line and by import 7 by a pump 40 coarse grain is separated, its outlet 9 is connected with a nozzle 42, this nozzle has the structure of excess pressure valve, when the lubricant-suspension input pressure surpasses a threshold pressure, open automatically, when not reaching threshold pressure, close.
The output pressure of pump 40 makes it to remain on certain intermittent pressure in intermittence between course of injection by a control device 43, when atomizing of liquids, be promoted to expulsion pressure, course of injection rolls back again on this intermittent pressure when stopping, intermittent pressure is wherein determined like this, is made it just in time be not enough to open nozzle 42.
Terminal point at course of injection, triple valve 26 is opened (and closing again) by control device 43 control before course of injection begins next time, make suspension flow through the inner chamber 24 of filter thereby scraping blade 17 and screen 11 are cleaned and the coarse grain (filter residue) in the inner chamber 24 are rinsed out by drain tube 27 along the direction perpendicular to armature spindle 22.
When the suspension coarse fraction is high, banked direction control valves 26 is corresponding to be communicated with waste way 45 more continually, so that coarse fodder fully gets rid of, at this moment, that yes is inconsiderable for open valve 26 too continually, because not only make undesired coarse grain but also (valuable) lubricant is also together drained.
Because import 7 is opposed mutually with the outlet 25 of slag liquid, together be in therebetween scraping blade 17 and the frequent unlatching of valve 26 (leading to pipeline 44 or 45), as previously mentioned, make scraping blade 17 cleaning especially by pour slot 28 and finished by liquid stream and formed eddy current that these outstanding scraping blades partly impact, its effect when the initial pressure of import 7 is very high is fine.This moment, the pressure in chamber 24 almost was unexpected decline when valve 26 is opened, and therefore forms a compression shock, thereby eddy current is strengthened, thereby cleaning performance is strengthened.At this moment rotor 14 drives by motor 12 together with scraping blade 17 and continues rotation, so wash liquid stream affacts on all scraping blades of diverse location, and promptly the difference by the scraping blade position acts on the scraping blade with different angles, and this helps to improve cleaning performance equally.Compression shock thereby cleaning performance finally not only act on scraping blade 17 but also act on sieve 11: liquid stream washes away the coarse grain that is not struck off by scraping blade 17 that exists on the sieve 11 to remove along sieve 11 abreast by flowing through inner chamber 24 suddenly.
